The Harvester is the mother ship of the Pioneer Drone that we built previously. It is meant to control the drones and use them to harvest resources.
When creating the drone, we used a previously built base mesh we detailed afterwards. With The Harvester, we'll now explore a new technique, introduced with ZBrush 4.0 — ShadowBox. This allows us to create a model by painting a cross section of all three sides. The next screenshot illustrates this principle. It may look confusing at the beginning, but once you get your head around it, blocking out mechanical models has never been easier. And it's tons of fun, really:
As you can see, the model is created by painting masks on all three sides of shadow box. Drawing masks goes quite fast, allowing us to do quick iterations in design. Let's see this technique in action.
